Abstract

To perform treatment by readily introducing a device causing minimal invasion even where approach from the body surface is difficult, a medical device includes a guide that is inserted into a lumen; a first balloon at a distal end of the guide, connected to a first flow path extending to a proximal end of the guide; a second balloon on the guide, separated from the first balloon on the proximal-end side and connected to a second flow path extending to the proximal end of the guide; a third balloon extending along the guide from a point between the first balloon and the second balloon to the proximal end and having a port for supplying or discharging fluid at the proximal end; and a cleansing flow path having a discharge port between the first balloon and the second balloon and extending to the proximal end of the guide.

Claims

1. A surgical method comprising:

a cleansing step of cleansing the interior of a lumen passing through the vicinity of an affected area;

an inserting step of inserting a surgical device from an opening of the lumen into the interior of the lumen cleansed in the cleansing step; and

a penetrating step of penetrating the luminal wall of the lumen with the surgical device in the vicinity of the affected area to advance the surgical device to the affected area.

2. A surgical device according to claim 1, further comprising a closing step of closing, prior to the cleansing step, the interior of the lumen at two points spaced apart from each other in the vicinity of the affected area,

wherein a closed space formed between the two points in the closing step is cleansed in the cleansing step.

3. A surgical method according to claim 2, wherein the closing step is performed by inflating balloons at the two points.

4. A surgical method according to claim 2, further comprising a route ensuring step of ensuring, prior to the inserting step, a route in the lumen from the closed space to the opening, the route being separated from the luminal wall of the lumen.

5. A surgical method according to claim 4, wherein the route ensuring step is performed by inflating an elongated balloon extending from the closed space to the opening.

6. A surgical method according to claim 1,

wherein the affected area is the back side of a heart, and

wherein the lumen is an esophagus.

7. A medical device comprising:

a guide member that is inserted into a lumen;

a first balloon provided at a distal end of the guide member and connected to a first flow path extending to a proximal end of the guide member;

a second balloon provided on the guide member at a point separated from the first balloon on the proximal-end side and connected to a second flow path extending to the proximal end of the guide member;

a third balloon extending along the guide member from a point between the first balloon and the second balloon to the proximal end and having a port for supplying or discharging fluid at the proximal end; and

a cleansing flow path having a discharge port between the first balloon and the second balloon and extending to the proximal end of the guide member.

8. A medical device according to claim 7, wherein the second balloon is provided movably along a lengthwise direction of the guide member.

9. A medical device according to claim 7, wherein the third balloon is provided such that the third balloon is attachable to and detachable from the guide member.

10. A medical device according to claim 8, further comprising a ring-shaped cover member that is attachable to and detachable from the outer circumferential surface of the second balloon and expandable in a radial direction in accordance with inflation of the second balloon.

11. A medical device according to claim 10, wherein the cover member is formed of a biodegradable material.
